“…A technology embodiment for the monitoring and control system against relay-protection hidden failures [27] was proposed by AG Phadke and JS Thorp of Virginia Tech in 1995, but it was not applied in industry since the technology was not mature enough. In 2004, a monitoring system was developed against hidden failures by the wide-area protection system, however was of poor reliability and the cost was high [28]. The detection of hidden failures depends on the running state of Power System [29].…”

With the construction of the ''3-level, 3-verticalline, and 1-circle'' power backbone in China, it's stricter and stricter on relay protection system and security and stability control system (SSCS) for reliable power transmission. Lots of blackouts in the world had happened, one main reason for which is the hidden failures of relay protection system or SSCS. Much work had been done about the hidden failure of relay protection, including classification, probability model, analysis methods of effects on power grid, and monitoring measures, which was summarized in the paper. The operation experiences of SSCS indicated that there might be hidden failures in five links of the security and stability control device (SSCD), e.g. measuring, control strategy, setting, communication and voting pattern. In addition, the coordination hidden failure among relay protection system, SSCS, and power plant's parameters related to the power grid was pointed out for more attention. In the future, amounts of work will be expected to be conducted on hidden failure: model building, assessment methods, application of research achievements, operation management of secondary equipment, and coordination problem between the relay protection system and the SSCS.

“…A design of wide area adaptive protection system whose role is to monitor and control all the relays in the substation is carried on to watch hidden failures in [52]. The Protection Setting Verify ing and Analysis System based on adaptive technology are widely used in power system to verify the relay setting, as in [53][54][55][56].…”

S tudies of major blackouts reveal that power system protection devices have contributed to a majority of system disturbances. As the most troublesome failure of relay protection, hidden failure needs more attention. In this paper, emphasis is placed on the importance of studies on hidden failure of relay protection which causes cascading failures. By clarifying the concept, characteristics and harmfulness of hidden failure, the paper proposes two response measures -vulnerability analysis and risk assessment, monitoring and control system, and draws a conclusion that the corporation of both could be the developing trend in the future.
